If I connect my laptop to the ISP router with a LAN cable, and do a speedtest online, I get near 40 Mbps upload speed.
If I connect the same LAN cable to the main Deco instead of directly to the router, so ROUTER---DECO---Laptop I get 10 Mbps upload.
So it seems that the Deco is limiting the upload speed greatly. Download is also smaller but still enough, upload concerns me more at this point.
Is this a known issue? Any advice?
